HARULD F JAcKs UN Patented Feb. 15, 1949 UNITED STATES PATENT- oFFicsWORK SUPPORTING MEANS FOR HEAT TREATING FURNACES Harold Jackson, Springfield, Ohio, assignor' to The Ohio Steel Foundry Company, Lima, Ohio, acorporation of Ohio Application August 2, 1946, Serial no. 688,129 8Claims. (01. 263-47) or uneven guiding rails, without danger ofbreakage.

' The primary object of the invention is the proshipment or storage whenin knockdown-condition. p

Further objects and advantagesv of theinvention will be apparent fromthe following detailed description and from the accompanying drawingsillustrating one embodiment of the invention, in which: Y

Fig. 1 is a top plan view of awork supporting means embodying theinvention, with parts broken away; Fig. 2" is a side elevation thereof;

with parts broken away and partially shown in dotted lines; Fig. 3 is anenlarged section on the line 3-3 in Fig. 1; Fig. 4 i an enlargedperspective view of one of the tray members; Figs. 5 and 6 are enlargedtop and side views, respectively, of one of the bars on which the traymembers are mounted; Figs. 7 and 8 are side and end views, respectively,of a supporting post for the superstructure by which the work issupported; Fig. 9 is an end elevation of the work support embodying .theinvention, and Figs. 10 and 11 are top and side views, respectively, ofthe post supporting link .members of' the base structure, with theasso-- together in spaced relation at their ends by respective side bars1, 1. Each bar I is disposed freely between pairs of spaced piston lugsBen the respective ends of each runner 5 and 6 and is loosely connectedto each pair of lugs by are-- spective rod 9. The rods 9 are mounted forfree lateral movements both in the lugs 8 and bars I, the apertures Illreceiving the rods. in the lugs being vertically elongated.

A pair of links or bars ll connect the rods 9 V on each runner 5 to therod 9 on the center runher, and these. links are quite widely spacedwith one adjacent toeach side bar I. The links I I are loosely mountedonthe rods between respective pairs of lug-s l2 on the runners 5 andlugs l3 on the center runners, with the rods freely movable ina'perturesin the lugs. 'lf'he inner endsoi. the adjacent links eachhave:sidewise lappingv relation between the respective lugs l3. Each rod 9'isprovided with one or morering welds H to limit its lengthwise movementin thelugs,

Each ,link III is provided, in longitudinally spaced relation'andpreferably near each end thereof with a vertical aperture l5 forreceiving the lower end studs [6 of'a respective post 3, so that thepost is supported in upright positionby the link in substantiallyrigidrelation thereto. These postsmay be of any'desired length to support thesuperstructure 2 in proper. elevated position. Each post 3. is providedat its upper end with a shoulder l1 and a stud I8 projecting up- Wardtherefrom.

The superstructure 2 comprises, in the present instance, a pair of bars20 spaced lengthwise of the runners and each in vertical register withthe respective setof longitudinally. aligned links H A plurality of trayor grid sections 22, ofrelon gated rectangular form,are mounted inadjacent side-by-side relation on andin connection with the bars 20crosswise thereof, as best shown in Fig. 1. These tray sections are ofsufficient-numher to substantially extendv from end to end of the bars20 and have their ends extending beyond the bars and preferablyterminating substantially in vertical'alignment with the side bars I ofthe base structure.

Each tray section 22 is provided over each bar 20 at the same half ofeach side edge with half round ears 24 and half round recesses 25 at theinner ends of the ears, with the recessbottoms the sections to retainthem in assembled relation on the bars.

5. In a work supporting means of the class described, a structurecomprising a plurality of transversely spaced bars, and a plurality oftray sections mounted side-by-side on said bars sub- 7stantia'llyithroughout their lengths, and supportproject through andabove the apertures-2 x in the bars 20 and into registering apertures 26incertain of the tray sections, thus serving'j'to loo'sely hold thesections in assembled relation "on said bars. Certain of the apertures26 are disposed intermediate the posts 3 and'thesereceive'lugs121projecting up from the bars 20. The traysections 22 are duplicates andcan, therefore, be made in tha in mold i be es e sa nes em 3 m re r v te. p s i e 1 p is s iee r lative'to a preceding section. "{fItis"apparerit"that the various parts of eabeseand.su erst u t re I, a 2 rloosely connected in :a mannerto rpermit relative flexing movementthereof so as to prevent breakage when warping or distorting of eitheror both structures take place by reason of any unevenness in thesupporting railstraversed by the runners and 6 or of heat conditions.All of the connecting joints of the various parts, with the exception ofthe connection of the parts 3 with the links H, are left loose to permitsuch flexing action and to prevent the transfer of strain from one partto another when any warpingor distortion takes place.

I .wish it understood that myinvention is not limited to any specificconstruction, arrangement or form of the parts, as it is capable ofnumerous modifications and changes without departing from the spirit ofthe claims.

Having thus described my invention, what I claim ,as new, and desire tosecure by United States Letters Patent, is:

1. 'In a work supporting means of the class described, a flexiblestructure having transversely spaced bars, and a plurality of traysecdescribed, a flexible structure having trans- 1versely spaced barsand a plurality of tray sec- 'tions of oblong rectangular form inside-by-side relation on said bars, said sections having loose lostmotion connection with each other and with -=said bars.

' 3.- A combination as called for in claim 2 to- 'ge'ther'with meansforming an elevated support for said structure. e V

'4. -In a worksupporting means of the class "described, astructurecomprising-a pluralityof transversely spaced bars and a plurality oftray sections mounted side-by-side on said bars substantially-throughouttheir lengths, andmea'ns on" the bars intcrengaging with at least someof of flexing movements relative to each other and ingon'eans forthebars having parts interengaging with at least some of the sections toretain them in assembled relation on the bars.

6. In a; work supporting means of the class described, a flexiblestructure comprising transversely spaced bars, and a plurality of traysections 1 of oblong-rectangular for-m mounted in side-by-side relationon said bars and capable to thebars, said sections being of duplicateform ears 'of an adjoining section, said lapping ears having registeringvertically disposed perforation'stherein, and stud means projectingabovesaid bars and freely'entering said apertures-"to retain the sections inassembled relation on the bars. my;
